Jack Dennerlein is a Professor in the Department of Physical Therapy at Northeastern University. His research aims to prevent work-related injuries and musculoskeletal disorders (MSDs) through multiple research approaches that in general examine how the design of the environment, both built and organizational, affects worker health outcomes. This research is based on a systems approach articulated through the goal of modern ergonomics, which is to optimize system performance and human wellbeing. His research study designs are both observational/descriptive and experimental, based in both the laboratory and in the real work environment.
